J. L.. luna-mussv DRAINING VALVE Filed Feb. 2, 1926 YPatented Mar. 15, 1927.

UNITE DRAINING VALVE.

Application vled `February This invention relates to a drain Vdevice and has for its object more vparticularly the provision of an improved draining valve for liquid or gaseous containers.

My improved draining valve is of lthe non-freezing variety, such as is described in my co-pending application, filed August 15, 1925, Serial No. 50,424, of which this application is a continuation in part..

That is to say, when the valve is installed and is in the closed position, there will be no contents of the container, towhich the valve is to be attached, within the draining valve to freeze and thereby clog the same. Assoon as the valve is turned o', it drains itself substantially dry.

In order to make my valve easily nonleakable in the most dificult situations, I make use of both threads and ground seats on the valve members. This combination is particularly advantageous when it is desired to use adraining valve in connection with liquids of exceedingly mobile Vqualities or with gases under high pressure.

This member is preferably in two main parts.V

isto be attached to the outside of the connected tothe insidestationary member part.

A` vent leads to the axial passage, through :i5 the stationary member, through which is conducted the contents of the containerwhen the valve is in the open position. Y

The' cooperatingmovable and stationaryl members are `both threaded and ground io seatedfin some appropriate manner so that the movable member can be drawn relatively.

to tliestationary member to open and close the vent. The' ground seats makevery close contact when the movable member is tightly drawn 'toward the stationary member by means of the threads. Moreover, the mutually tight fitting threads on the valve members tend to keep the ground seats tightly Vcontacting with one another when' the valve `isin the closed position.

Suitable means are provided at the end i of the outside stationary/member part, asV

a turning wheel or-bar attached to a stem leading through the axialpassage' and fitting into vthe cap end. of the movable member, for moving the movablemember rela-Y Thus, I employ a stationary valve member having'an axial passage therethrough.

One part is to be attached to the. inside of the container, while the other part 2, 1926. Serial No. 85,422.

tively to the stationary member to open and close `the vent :or vents. These turning means may be either permanentlyattached or detachable. In order to make the valve safer as in the case of an oil tank, may be drained at Ydifferent levels, adjustable meansfare provided for conducting the contents from any desired level, to the drainingvalve attached to the container.

My improved drain valve will Vbe more clearlyl understood by reference to the ac` companying draw-ings, taken in connection with the following description, in which.:

F1g..l isa sectional elevation of avalve` attached to a container', showing thev valve 80 in the closed position'. v

Fig. 2 is a sectional elevationV of the same valve in the open position.- v l I f -The movable. member 1', preferably madel of brass, is appropriately threaded for 421.85 short distance 2, adjacent tothe ground lseat, 3. ThisV movable member hasV asuitable; pocket or socket 4, into which a wrench ory turningmeans can bey inserted. `The ground s eat is carefully threaded to itsnugly' 90 Epon the ground seat of thestationary meniel', I

The stationary member part 5 is appropriately'A threaded over a` distance r6, so that the movable member 1, may be screwed back The threaded end 13 is designed to fit into 105 the pipe flange 14 secured to the container 15V by means kof the rivets y16.= The lock washer 17 isy used to drawVl the stationary member part 5 so tightly into the pipe flange 14, that the same will remain immovable during the` Aturning' of the movable member.

i The feeding cylinder 12 is of such dimensions as to completely cover the movable member 1 in its closed as well as in its open position. It is preferably of such length` that the closedend of the movable member vwill bear against Athe closed end of this cyl inder when theV movable member is in the.

f Y bow 19 fits loosely into the cylinder so that the pipe Vconduit 18 may be lifted or lowered to any desired level within the container. y

YA hole 20 lis placed in the container 15 in line Vwith the axial Ypassageway of the stationary member part within the con; tainer, as well as the stationary member part 21, attached to the outside of the container. AOne end'of the Youtside stationary member part 21 isthreaded at 22 to lit snuglyvand unlealrably into the pipe flange 23, attached to t-lie container by means of the rivets 16.

The other endV of the youtside stationary member partis threaded at 24 to receive the T 26. An outlet pipe 27 fits into the lower portion of the T.V i

The other end of the T is fitted wit-h a Abushing 28 containingy packing material 29,

'androutside stationary member parts). thisy manner -an unimpeded passageway is provided Vfor the inflowing oontentsof the` VVover whichis screwed the bushing cap 30.

A turning wrench or stem 31 equipped with a head 32, designed toy fit into the socket -4 of the movable member 1, makes up one i Vend thereof. This turning stem equipped at'the other or outside end thereof with a turning rod or wheel 33. While this turningfstem may be permanently attached to the movable member 1, it is preferable to have itdetachable, so that the main body of the stem canv be completely withdra-wn from the axial passageway of Vthe stationary member (comprising the Vinside In container, when the v'movable' member of the Ydraining valve is in the open position.

Moreover, in orde-r to makethis draining valve substantially fool-proof the bushing drain off some of its contents, lthe turning stemV head -32 is pushedY into the socket 4,

of the movable member 1.l An appropriate number of turns will `put the movable meniy ber 1 beyond the vent 7 in the stationary As soon'asjthe vent 7 is open, the contents ofthe container, passing down throughY Y the adjustable conduit 18, floods the interior of the feeding cylinder 12, `and the saine rushes down into theV axial passageway 8.

In orderl to provide a more free andiniimpededpassageway for the outfiow ofthe contents of the container, the turning stem 81 is preferably withdrawn as' far as'possible. That is, `until the head 32 strikes against thebushino 28. The contentsof the container thenl fiow'tlirough the axial passageway into the T 26 and down the outlet Vpipe 27. Y, p Y

After aV suitable amount of the contents of the container have been withdrawn, the detachable stein 31 isA againslioved back into vthesoclret 4 of the' movable member- 1. A'n

appropriate Vnumber of turns in the reverse 'direction' again putsthe draining valve in the closed position. If desired, the bushing 28 may be removed from the T 26, which will also carry withitthe turning stem 31. A plug of anyconventional make may then be inserted into the end of the T left open by thel removal of the bushing, in order to close the same. j

The use of the lfeedingcylinder 12 is op-V tional. .'Ihis feeding device is merely provided for those situations in Vwhich it is desirable to withdraw conten'tsfofl the con vUi tainer from different levels. Let iis suppose that the contain-er is filled with oil and water. Since oil will float upon water, the

container will have at least two Vstratumsl Aof f Vliquids--one ofwater and the other of oil.V VIf Athe operator wishes to removeV oil, and

not. water, he merely pulls `the adjustable' conduit 18 up to the o ilrstratum. I/Vhen that is done, oil can be withdrawnv from the tank as soonv as the ydraining valve isput into theopen position.'

It is to be understood that my invention is not to be confined to the onesingle forni of valve that I haveillustrated in the accom panying drawings and described in this specification. Variations of structure are possible without deviatingfrom the principles or spirit of my discovery. I have made use of the combined features of threads and ground seats in a draining'valve to receive the other, and means for moving l f the movable Ymember relatively to the sta-V tionary member to open and close the vent, the ground seats being in engagement When the valve is closed.
